Overview and Dimensions
iMac Retina 4․5K 24″ was released by Apple on April 20, 2021 and is powered by macOS OS. By default, the device is shipped with a web browser — Safari for macOS. Device dimensions are 547 × 461 × 147 millimeters (21.5 × 18.1 × 5.8 inches) 1. The device weighs 4460 g.
iMac Retina 4․5K 24″ has a large-sized 4.5K Retina Display display with a 24-inch screen (1518.8 cm2, 16:9 aspect ratio), and an approximate 60.2% screen-to-body ratio. The display is a not touch screen, touch events are not supported.
Screen size, Viewport, CSS Pixel Ratio
iMac Retina 4․5K 24″ has a 24-inch screen with a screen size (resolution): 2240px × 1260px, 2240px × 1260px viewport1, and a CSS Pixel Ratio of 2.
Viewport or Viewport size is the number of software pixels (CSS pixels) present on a screen. Usually, viewport size displays as viewport width in pixels to viewport height in pixels.
Device Pixel Ratio (DPR) or CSS Pixel Ratio is the ratio between the physical pixels (screen size or resolution) and CSS pixels (viewport). Depending on device specification, one CSS pixel can equal one or mode physical pixels. Modern devices have screens with high pixel density resulting in the difference between screen size (resolution) and viewport.
Viewport size = Screen Size (Resolution) / Device Pixel Ratio.
CSS Pixel Ratio = Screen Size (Resolution) / Viewport size.
Key points for development and testing on iMac Retina 4․5K 24″
Before you start web development or testing, check that the web application supports a responsive viewport by using a viewport meta tag:
<meta name="viewport" content="width=device-width">.
You can inspect this tag in the head section of an HTML document on iMac Retina 4․5K 24″ right in the Blisk app. If this viewport tag is missing, the web application will not be responsive and will overflow the screen, hiding the content from users and leading to a bad user experience.
The form factor of the device represents its primary orientation as a landscape. Portrait orientation is not so popular on desktops as on mobiles.
You also need to consider that desktops are usually manipulated with a mouse, keyboard, and touchpad. To develop a high-quality web application, the developer should keep in mind the way the application responds to the actions of a user on hovers, clicks, drag and drop, focus events, etc. It has become a good practice to use mobile-like behaviors on desktops (e.g. swipe event on a slider). The majority of modern touchpads allow using multi-gestures on laptops and desktops.
